The present disclosure is directed to overhead door assemblies and operating systems. Disclosed herein is a drive drum that is compatible across a variety of overhead door types, including, for example, standard lift doors, vertical lift doors, and high lift doors. The drive drum of the present disclosure comprises a first cable groove section and a second cable groove section, opposite the first cable groove section, wherein at least one of the first cable groove section or the second cable groove section is in a non-linear graduated arrangement.

A handle assembly for a door or window comprises a handle and a second element, installable on opposite sides of the door or window, and a pin element rotatable around a pin rotation axis and insertable into the handle or in the second element at variable depths. The handle assembly further comprises a friction reducing group positioned coaxially to the pin element and positionable between the handle and the door or window in the axial direction of the pin rotation axis. Clamping devices constrain the handle and/or the second element on the pin element at adjustable distances along the axial direction according to the thickness of the door or window, so that when the handle assembly is installed on the door or window, an axial clamping pressure of the handle and of the second element is maintained on the respective side of the door or window. An installation method of the handle assembly on the door or window is also provided.

A furniture fitting includes at least one rotatably mounted screw for fixing the furniture fitting to a furniture part. The furniture fitting further includes at least one drive element separate from the screw, and the drive element is movement-coupled to the screw and has a tool receiving device. The at least one screw is configured to be driven by rotating the tool receiving device with the aid of a tool.

A protective enclosure for a food protection system includes a first hinge member, a second hinge member rotatably coupled to the first hinge member, and a coupler selectively repositionable relative to the first hinge member between an engaged position and a disengaged position. In the engaged position, the coupler engages the first hinge member to limit rotation of the coupler relative to the first hinge member. In the disengaged position, the coupler is free to rotate relative to the first hinge member. The coupler is rotatably coupled to the second hinge member such that (a) rotation of the coupler relative to the second hinge member in a first rotational direction is limited and (b) the coupler is free to rotate relative to the second hinge member in a second rotational direction opposite the first rotational direction.

An inverted constant force window balance system has a carrier assembly including a housing with a first and a second housing wall, a coil spring with a free end, and a shoe assembly slidably coupled to the housing. The shoe assembly includes a first and a second shoe face. The housing slides between a first and a second position relative to the shoe assembly. When in the first position, the first and second housing walls are substantially non-coplanar with the first shoe face, and when in the second position, the first housing wall is substantially coplanar with the first shoe face and substantially non-coplanar with the second shoe face. The shoe assembly receives a pivot bar from a window sash and extends a brake upon rotation thereof. The balance system also includes a mounting bracket releasably coupled to the housing and coupled to the free end of the coil spring.

After the claims, please insert a page containing the Abstract of the Disclosure which is attached hereto as a separately typed page.

A multi-piece hinge cap covers an upper surface of an installed geared continuous hinge to provide ligature resistance with a door supported by the installed geared continuous hinge in a closed position. The multi-piece hinge cap has a frame cap that attaches at a vertical member of a door frame above a frame leaf of the installed geared continuous hinge. Also, the multi-piece hinge cap has a door cap that attaches at the door adjacent to the frame cap and above a door leaf of the installed geared continuous hinge. The frame and door caps each include an upper surface having a downward sloping angle that slopes downward from the door frame and the door, respectively, and extends over the exposed upper surface of the installed geared continuous hinge.

Disclosed is an air conditioner including a first frame including a through hole, a second frame rotatably coupleable to the first frame, the second frame including a burring portion at least a portion of which is insertable into the through-hole in a first direction, where while the burring portion is inserted into the through-hole of the first frame, the burring portion protrudes in the first direction, and a burring hole formed by the burring portion, and a fastening member insertable into the burring hole in a second direction opposite to the first direction and configured to function as a rotary shaft of the second frame, where while the fastening member is inserted into the burring hole, the fastening member protrudes in the second direction.
